I'm trying to sign an application who uses a 3rd party DLL (actually a python module). If i sign it using a developer certificate, it works right, but when I try to use Express Signed, it gives me a UID error. I supose that the DLL has an UID that is not in the range I reserved.
If I change the UID of the application with "ensymble.py altere32" the aplication can be signed via Express Signed and can be installed, but it fails when i try to run it in the phone.

What can I do to use this DLL in my own proyect and get it signed?

Best regards.
